Is this single fuel filter, pre or post the pump?
I would like to add a primary filter to the mix.
Anyone have a suggestion? pc
The FS1212 is your primary fuel filter (between tank and lift pump). A quick check showed it to be a 14 micron filter-- a good choice for a primary filter.
You also have a secondary fuel filter (between lift pump and engine).
The filter I find is over the 3 start batteries (FS1212) easy to service.
As for the 2nd filter you mention, I'm not seeing it (must be hiding someplace I'm not looking.) pc
The filter over the start batteries is your Winn water separator and prefilter.
The. Main filter should be on the right side of the engine near the air pump.
Sorry no, on this 320 the FS1212 is where the Winn should be..
it must have gone on a vacation, because it is nowhere to be seen. pc
Here is what my 8.3 parts book from Cummins says
Filter Location: Under Head Cylinder #5
Absolute Filtration (microns): 25
Compatible with Lift Pump: Yes
Air Heater Connection Provided: No
Filter Inlet Diameter: 1/2 Inch
Engine Family: C Series
Engine Cylinders: 6
Like wolfe10 says.........the filter you see is your pre-filter/water seperator/primary filter.....whatever you wanna call it. The OEM filter Cummins installed is attached TO the engine on the starboard side.
Now.....if the PRE-FILTER is 14 microns and the Cummins filter is 25 microns it stands to reason that you will not need to change the secondary filter due to the pre-filter having smaller pores. Anything that gets thru that filter will get thru the engine.
I have a different motorhome than you, so all of this info may not apply but I think it does.
For us landlubbers, which side is that?
Thanks,
Trent
Trent,
Starboard should be passenger side.
I have a 1995 U320. The secondary filter is on the engine such that to see it one needs to be under looking up.
Just had all my filters replaced, chassis greased and engine oil replaced for $300 by mobile service at my pad.
During the battle of Britain, a brash young aviator was in a posh London restaurant. He asked the waiter for a glass of red port wine.
The waiter sniffed and replied "sorry, we have no red port left"
red light, left side, port
green light, right side, starboard.
Works for aircraft too. You can tell if a plane or boat is coming or going by the position of the lights.
Rudy,
Thank you.
I know some of the members have or had boats, but many of us have not. I would suggest that the Foreforums messages use "driver" or " passenger" sides when referring to our RV's. After a bit of thinking, I can probably figure out which is curb side and which is street side, but it does not come naturally to me.
I have always thought that English was the national language for the US, but Congress cannot agree on that (as well as many other things). Some battles just aren't worth fighting, apparently.
However, while we are on the subject, which side of the RV is the right side? Which side of the engine is the right side?
Thanks,
Trent
Rudy,
Would you share contact info for your mobile service provider?
BTW I very much enjoyed watching you perform that elegant Aqua Hot filler neck fix at Xtreme.
David
Dependable on which way you are facing the coach!😀
So each of us could be standing beside an RV, discussing the right side, and we could each be talking about a different side?
Trent
And that's why we have Port and Starboard on boats. Port is always the left side looking from the rear towards the front.. We use port and starboard when giving maneuvering directions. No confusion that way.
FYI: Port was once called Larboard, as in laden side or lading (loading) side. But was never used for steering commands as it was too easily confused with starboard.

.......and that's why I used starboard. You can google a word rather than hijack the gentleman's thread.
We have the same engine. Here's a photo of mine. Near the rear of the engine on the right/pax/starboard side. If you crawl under there almost to the back of the coach, I think you will see one something like this.

Hi David,
Enjoyed your supervision at Xtreme.
I used Robert who has a mobile RV oil and filter change service. HIs truck is really set up for the job. His number is 7 one 3 859 zero 859. Price depends on what you want done. He goes all over southeast Texas.
jor,
Do you have the PN for that Fleetguard secondary/fine fuel filter?
I am having trouble believing that Cummins would spec a 25 micron as a secondary filter (primary, sure).
Of course I could have, but I was trying to make a point. I think I was able to during the subsequent discussion.
Raising the question when the term was used allowed everyone to learn the meaning, not just the questioner.
Thank you for your positive contribution to Foreforums.
Trent
Keith,
Thank you for the succinct explanation.

If your referring to the M11 Cummins fuel filter that screws on the starboard side in a vertical position, I use the FS1000, there are many will fits. This filter is the last filter on the engine, I also use the Winn as first filter in the lne.
Yip, that's the one I'm using too - the Fleetguard FS1000. I used this one on both my 95 and 99 M11s. I did a quick query on it and came up with this.
The FS1000 shows to be a 5 micron element. That makes perfect sense.
FS1000 is the updated FS1212 filter (per Mr.Wash w/Fleetguard.)
10 microns @ 90 GPH w/98.7% efficiency.. pc
